Description
The utility model relates to the inner climbing jacket frame lift system of tower crane auxiliary device, particularly a kind of internal-climbing tower crane.
Existing internal-climbing tower crane climbing device is divided into side jacking and two kinds of patterns of central jacking, adopt the tower machine of side jacking, climb in every once need successively upstairs to remove Hydraulic Station, hydraulic ram, in climb framework and bearing beam, not only labor strength is big, and the dismounting trouble, time-consuming.Need not move Hydraulic Station and hydraulic ram though adopt the tower machine of central jacking, but still climb framework, bearing beam and cat ladder in needing to remove in the dismounting, in order to climb framework and bearing beam in installing, often to do specific (special) requirements to the design and construction of elevator, both waste materials, increase cost again, so that have influence on promoting the use of of internally climbing tower crane.
Patent application (the patent No.: 98228957.X) that the applicant once proposed a kind of " internal-climbing tower crane climbing device ", by inner climbing jacket frame, hydraulic lifting mechanism, crossbeam, internal climbing foundation is formed, inner climbing jacket frame is a tower structure, both sides are provided with cat ladder, integral assembling is on body of the tower, body of the tower places in the elevator of building, this technical scheme has solved the problem that existing internally climbing tower crane climbing device exists preferably, but still find to exist some problems in the practice, as it is also unsatisfactory to promote inner climbing jacket frame mechanism, because the hoisting speed of winch is too fast, inner climbing jacket frame stability in the process of climbing is not enough, meet obstacle and can't in time find again and eliminating rapidly, cause accident to take place easily.
The purpose of this utility model is on the basis of existing internally climbing tower crane climbing device, problem at its existence, develop a kind of new internal-climbing tower crane inner climbing jacket frame lift system, the advantage in order to further bringing into play internally climbing tower crane makes it to be more widely used in high-building construction.
The purpose of this utility model is achieved through the following technical solutions:
The inner climbing jacket frame lift system is characterized in that:
A. be provided with the lifting crossbeam in the standard knot on body of the tower top, stretch out outside the body of the tower standard knot at the two ends that promote crossbeam, and its termination is equipped with wheel flutter;
B. wheel flutter is provided with chain, and an end of chain is fixed on two straight beams of inner climbing jacket frame, and the other end passes and turns to race, and hanging is to the both sides of jacking crossbeam;
C. below inner climbing jacket frame, be provided with guide frame, link to each other by hanging steel disc between inner climbing jacket frame and the guide frame;
D. be provided with hook at the two ends of entablatrance and jacking crossbeam.
Four jiaos at inner climbing jacket frame and guide frame are provided with track adjusting wheel.
According to the inner climbing jacket frame lift system that the utility model proposes, the top lift that utilizes hydraulic lifting mechanism dexterously is as promoting power, make inner climbing jacket frame existing enough propulsions source in lifting process, can promote by pulsation-free again, thereby can get rid of various obstacles and the resistance that runs in the inner climbing jacket frame lifting process effectively, save a twin drum winch and relevant electric equipment simultaneously, reach purpose safe and reliable and the reduction manufacturing cost.
Fig. 1 is the running condition scheme drawing that the utility model is used for internally climbing tower crane;
Fig. 2 is the structural representation of inner climbing jacket frame lift system.
The utility model will be further described according to accompanying drawing embodiment below:
As shown in Figure 1 and Figure 2, internal-climbing tower crane mainly by the internal-climbing tower crane pylom and in climb mechanism's two major parts and constitute.Wherein pylom by base, body of the tower, tower cap, crane arm, equilibrium arm and hoist, luffing, revolution and hydraulic mechanism etc. form.In climb mechanism and partly form by inner climbing jacket frame 13, hydraulic lifting mechanism 9, entablatrance 10, jacking crossbeam 8, internal climbing foundation 7 (forming), cat ladder 11 etc. with the transformation of pylom base.Inner climbing jacket frame 13 is a tower structure, and both sides are provided with cat ladder 11, and integral assembling is on body of the tower 14, and body of the tower 14 places in the elevator of building.In when climbing operation, internal climbing foundation 7, entablatrance 10, jacking crossbeam 8, hydraulic lifting mechanism 9 all climb with pylom, inner climbing jacket frame 13 and cat ladder 11 etc. then places outside the pylom, must use a kind of lift system that it is upwards promoted.
The inner climbing jacket frame lift system that the utility model proposed is exactly to climb on the mechanism basis in internally climbing tower crane is existing, for being provided with interior devices such as inner climbing jacket frame and cat ladder are upwards promoted when climbing operation, it is that (approximately apart from about 25 meters of tower machine bases) is provided with lifting crossbeam 1 in the standard knot on body of the tower 14 tops, stretch out outside the body of the tower standard knot at the two ends that promote crossbeam 1, its two ends all is equipped with wheel flutter 2, wheel flutter 2 is provided with chain 3, about about 35 meters of chain length, the one end is fixed on two straight beams of inner climbing jacket frame 13, the other end passes the race of wheel flutter 2, hanging is to the both sides of jacking crossbeam 8, guide frame 12 is set below inner climbing jacket frame 13, hanging steel disc 5 by four between inner climbing jacket frame 13 and the guide frame 12 links to each other, be provided with hook 6 at the two ends of entablatrance 10 and jacking crossbeam 8, the hook 6 of this example adopts short chain to be fixed in the two ends of entablatrance 10 and jacking crossbeam 8, hangs respectively during the jacking operation in the hole of people's chain 3, changes step to use for inner climbing jacket frame lifting and hydraulic pressure lift.
Four jiaos at inner climbing jacket frame 13 and guide frame 12 are provided with 12 track adjusting wheels 4 altogether, be installed in the straight beam inboard of inner climbing jacket frame and guide frame, corresponding up and down, the maintenance level rose when inner climbing jacket frame 13 was promoted, thereby made the cat ladder vertical uplift that is vertically mounted on the inner climbing jacket frame.
When being applied to promote, utilize hydraulic lifting mechanism 9 with the 8 downward jackings of jacking crossbeam, the hook 6 at jacking crossbeam 8 two ends tangles the lower ends downward of chain 3 and draws, at this moment, promote crossbeam 1 and born the downward top lift of piston rod in the hydraulic ram, turn to through wheel flutter 2 again, be delivered on the inner climbing jacket frame 13, inner climbing jacket frame is upwards promoted.Simultaneously, the cat ladder 11 that is fixed on 13 liang of straight beams of inner climbing jacket frame rises thereupon, and guide frame 12 also rises thereupon.
1～1.5 meter of the each jacking downwards of hydraulic ram, inner climbing jacket frame is just carried 1～1.5 meter by counter pulling on, and when jacking stops, hanging in the hole of both sides chain 3 with the hook at entablatrance 10 two ends, and chain is held, and makes the unlikely downslide of inner climbing jacket frame.Subsequently, starting hydraulic lifting mechanism 9 allows jacking cylinder drive on the jacking crossbeam 8 to carry, and the two ends of jacking crossbeam 8 hook taken out from the chain cylindrical void of being hung, treat that jacking cylinder all regains, when mentioning on the jacking crossbeam, again the two ends hook is hung in the chain cylindrical void, push up downwards about 10 centimetres, taking-up entablatrance two ends hang over the hook in the chain cylindrical void, have promptly finished changing step of a jacking.
After jacking is changed step several times, be about to inner climbing jacket frame and upwards promote 10--12 rice, concordant with the embedded box that is embedded in hoistway wall, at this moment, telescopic outrigger in inner climbing jacket frame two straight beams is pulled out the embedded box that places hoistway wall, just finished the lifting of an inner climbing jacket frame.
